一种改进的多源异类航迹关联方法

为了克服在多传感器信息融合系统中各类传感器的探测精度差异性很大以及异类航迹关联常常面临高不确定性的问题,提出了将证据理论引入到多因素模糊综合决策航迹关联中.利用证据理论进行不确定信息证据合成,再根据多因素模糊综合决策隶属度函数获取证据,解决了航迹关联的不确定性和证据理论在证据获取时存在的困难.实验结果表明:采用该方法的异类航迹关联能够有效克服证据合成过程中的不确定性,降低错漏关联率.

Improved Method for Multi-Source and Heterogeneous Track Correlation

In order to get over those problems that the detection accuracy of various sensors in multi-sensor information fusion system is completely different and heterogeneous track correlation confronts usually a high uncertainty, this paper proposes to introduce the evidence theory into track correlation with multi-factor fuzzy synthesized decision-making, where the uncertainty information evidences are combined by using the evidence theory, and the evidence is obtained on the basis of membership function of multi-factor fuzzy synthesized decision-making, thus working out the uncertainty of track correlation and the thorn of acquiring the evidence by evidence theory. Experimental results indicate that using the proposed method for heterogeneous track correlation could overcome effectively the uncertainty in the process of evidence combination and lower the error and missing correlation rate.
